I just finished my custom CP for the multi-game a few days ago. Using
the Tempest spinner & Clay's single player interface worked fine for me.
I does seem a little more sensitive...but I'v never played these games
before. If you spin it real fast, you do get get a stalling effect,
like
you describe. Here's how I hooked it up to the single player interface;

pin 1 on P30 -->dir
pin 2 on P30 -->neg
pin 3 on P30 -->+5v
pin 4 on P30 -->clk
pin 5-rest...-->fire,thrust,warp,etc..

looking at the bottom of Tempest spinner, shaft pointing
away from you & with the 4 pin conn at the left;

4 pin conn-->dir
4 pin conn-->+5v
4 pin conn-->neg
4 pin conn-->clk
  
I hope this helps.
